ABSTRACT:
A reaction-distillation method is provided in which a chemical reaction and fractionation are conducted in an apparatus having at least one reaction-distillation zone (A,B) including at least one bed of solid elements disposed on a fluid-permeable support (5) having perforations small enough to retain the elements. The bed of solid elements includes loose solid catalytic particles (2) and at least one receptacle (3), containing at least one distillation packing body (4). The external jacket of the at least one receptacle (3) is permeable to fluids and impermeable to the solid catalytic particles (2) and the packing body (4). The apparatus can be used for carrying out chemical reactions and concomitant fractionation of the reaction mixture, for example, to synthesize ethers from olefins and alcohols.
